BISC160 HOMEWORK 3: BPA CELLULAR RESPIRATION AND ENZYMES. Bisphenol A (BPA) is an organic compound (Fig. 1A) used to make a variety of plastics including those used to make plastic bottles (Fig. 1B). When BPA is released into the environment from plastics in landfills or litter, it has a wide range of effects on communities and ecosystems. Research has shown that it is toxic to algae, fish and invertebrates. In humans, it can disrupt the endocrine system by mimicking estrogen and increasing the chances of developing some types of cancer. Direct consumption can be avoided by using BPA free plastics for food and water, but we still could be exposed to BPA after it is released into the environment and absorbed into the foods that we eat. Therefore, it is important to understand how BPA enters our food and how it alters their physiology. Question 1: What is the chemical formula of BPA? Which functional groups are found in the molecule? In Figure 1, circle the polar portions of the molecule. Based on its structure, can BPA dissolve in water? Question 2: BPA can have effects on individuals, populations, communities and ecosystems. What is the difference between each of these levels of Biological Organization? Individual: Population: Community: Ecosystem: Even though plants are a large part of our diet, we know only a small amount about how BPA influences plants. Plants bring water, minerals (such as Potassium and Magnesium) and other compounds into the plant through their roots (Fig. 2). Therefore, BPA that is

Using the data in Table 1, what BMI score has 36% of the other observations greater than it? Round answers to nearest hundredth kg/m 2 (i.e. 23.43 kg/m 2). The value of kg/m 2 has 36% of BMI scores great than it. Table 1 BMI Scores (kg/m^2) 21.65 39.98 19.43 47.24 26.13 24.96 25.68 24.96 17.84 29.83 26.33 29.71 22.13 44.6 26.21 26.36 23.5 24.22 26.41 29.21 41.3 41.09 20.82 20.34 23.5 22.13 26.41 20.82 23.5 33.89
